The electrocardiogram in primary coccidioidomycosis.

Because in some cases of primary pulmonary coccidioidomycosis the principal complaint is pain in the chest resembling that of angina pectoris or coronary occlusion, the electrocardiograms of 20 cases of primary pulmonary coccidioidomycosis were studied, early in the illness and after recovery. In fifteen cases, no electrocardiographic abnormalities were noted. In five cases, findings during the acute illness differed from those after recovery. The changes noted were inversion of T waves and low voltages during the illness, reverting to upright T waves and normal amplitudes after recovery. In none of the cases studied were abnormalities found which might be confused with the electrocardiographic findings in angina pectoris or coronary artery occlusion.
